Inkohlakalo Yentliziyo Ekuzalweni
Isitya esikhulu segazi emzimbeni kunye nomphambili ophethe igazi ngaphandle kwentliziyo emzimbeni yi-aorta. Ngokubambisana kwe-aorta, intsilelo yesimo senhliziyo ekuzalweni, icandelo le-aorta lincinci (lugqityiwe). Oku kwenza kube nzima ukuba intliziyo iphephe igazi kumzimba.
Ukubambisana kwe-aorta kwenzeka ngo-5-8% wabantwana abazalwa benesiphako senhliziyo (ebizwa ngokuba nesifo senhliziyo esiswini).
Kubakho kabini rhoqo kubafana abafana namantombazana. Ukubambisana kwe-aorta kwenzeka ngenxa yokuba inqanawa ayizange iqhubeke kakuhle ngexesha leveki zokuqala zokukhulelwa. Esi siphene sentliziyo siqhelekileyo kubantu abaneengxaki ezithile zezofuzo ezifana ne- Turner syndrome . Ngokuqhelekileyo ixilongwe kubantwana kunye nabantu abadala abangaphantsi kweminyaka engama-40.
Iimpawu
I-aorta ifakwe njengomjeko we-candy, kunye nengxenye ephilileyo eya entloko kunye nenxalenye eqondekileyo ekhomba phantsi emzimbeni. Ukubambisana kwe-aorta kunokwenzeka naphi na kuyo kwinqanawa kodwa kulandeleka ukuba kwenzeke emva nje kwekhasi eliyi-C phezulu (ebizwa ngokuba ngumthi we-aortic). Oku kuthetha ukuba igazi linokuba nzima ukuphuma emzimbeni. Kwakhona, uxinzelelo lwegazi luya kuba phezulu phambi kwecandelo elincinane kodwa liphantsi emva kwalo. Ngako oko, abantwana abane-coarctation ye-aorta banokuba neempawu ezifana:
- iintloko ezivela kwingcinezelo yegazi ephezulu entloko
- iinyawo ezinobandayo okanye imilenze
- ukutyumba emilenzeni kunye nokusebenza
- izandi zentliziyo ezingavamile (intliziyo igungqeleka)
- utywala okanye utyhafile
- Iintsana zinokuba nobunzima bokutya kunye nobutyebi bokunciphisa umzimba
Xa kunzima kakhulu ukunciphisa, iimpawu ziza kuba nzima kakhulu. Ukunciphisa okulula kungabangela iimpawu.
Ukuxilongwa
Ngamanye amaxesha ukuhlanganiswa kwe-aorta kufumaneka ngexesha loviwo lokuqala lokuzalwa kwintsana okanye ngexesha lokuhlola isifo sesifo somntwana.
Ngamanye amaxesha iimpawu ezinjengeentliziyo ezibubulayo, iintloko, okanye ukusabalalisa kakuhle kwimilenze kuya kubonisa ukuba ukuxilongwa. Ingcali yentliziyo yezingane (i -cardiologist yabantwana ) iya kunika umntwana ukuhlolwa kwentliziyo epheleleyo, kubandakanywa ukujonga ukutshiza nokuxinzelelwa kwegazi kwiingalo nasemilenzeni. Ngokubambisana kwe-aorta, i-pulse iya kubuthakathaka kwaye uxinzelelo lwegazi lusezantsi emilenzeni kunezandla.
I-x-ray yesifuba ingabonisa isigaba esincinci se-aorta. Inkqubo enoncedo kakhulu iya kuba yi-ultrasound yentliziyo (echocardiogram). Kule nkqubo, i-cardiologist izakukwazi ukujonga isakhiwo senhliziyo kwaye ibone ukudibanisa kwe-aorta. Ngamanye amaxesha ezinye iimvavanyo ezinjenge-imagination magontic resonance (MRI) okanye i-computed tomography (CT) kufuneka ifunekayo ukuqinisekisa ukuxilongwa.
Unyango
Ukubambisana kwe-aorta kuphathwa ngokulungisa isigaba esincinci sesitya. Uninzi lwabantwana luya kulungiswa ngokusesikweni, kwaye phantse bonke baya kulungiswa ngaphambi kweminyaka eyi-10. Kukho iindlela ezimbini ezingalungiswa ngayo: nge-balloon angioplasty kunye nokuhlinzwa ngentliziyo evulekile.
I-balloon angioplasty - Kule nkqubo, ityhubhu ende eguquguqukayo (ebizwa ngokuba yi-catheter) ifakwe kwisitya esikhulu segazi kwi-groin kwaye ifakwe kwi ntliziyo ukuya apho i-aorta iyancipha khona.
I-catheter ine-ballo encinci ekupheleni kwayo. Xa lifika kwicandelo elincinci, ibhaluni iyahluthwa kwaye inxalenye encinci ivuliwe. Ifowuni encinci ebizwa ngokuba yi-stent ingafakwa apho ukukunceda ukugcina i-aorta ivule.
Ukuhlinzwa - Inxalenye encinci ye-aorta iyanqunyulwa kwaye iziphelo eziphilileyo zihlangene kunye. Ukuba icandelo lisuswe likhulu, izinto eziphathekayo okanye enye yemithambo yegazi iyasetyenziselwa ukudibanisa i-gap.
Uninzi lwabantwana luhlala ubomi obuphilileyo emva kokulungiswa kobambiswano. Ngamanye amaxesha ukucuthwa kwe-aorta kwenzeka kwakhona. Kule meko i-angioplasty ibhaluni okanye utyando olongezelelweyo lungafuneka ukuba lulungiswe.
